Cutting tools on steel .

Tool needs to be small tooth , so force is low . .

Then speed it up .. Carbide does higher speed than M2 HSS .

You are using big cutters , use 1/4" carbide , 4 flute .



You can reduce the force by using a tiny

cutter , some thing that pulls out a chip ,

with little HorsePower .

Luddite liberal designed Mills need torque breakover clutches .

1) clutch ( cause operators are never perfect)

2) very low pressure of cutter against workpiece . This means
speeding
up and less tooth ., small diameter ..
carbide allows higher speeds , clutch protects tool , if operator
hand feeds ..

3) Obviously 4 flutes are better than 2 ! Cause cutter must enter
cut at perfect speed , so 2 flutes take twice as long to cut , nobody
has
that patience .







Image a cheap 18vdc 550 RPM VAR-speed cordless drill , with
breakover clutch ,, tiny 4 flute , 3/16" carbide cutter , in DIY
mill .

Clever ...
